XHS Cover Generator
Generate publication-ready Xiaohongshu (小红书) cover images (1080×1440, 3:4 ratio) with Chinese text overlays.
How It Works
- Base image: Either AI-generated via Pollinations.ai (
--base-prompt) or solid color background - Text overlay: Chinese text rendered with Noto Sans CJK font via PIL (auto-downloaded on first run)
- Output: JPEG at 95% quality, ready to post
Styles
| Style | Use Case | Example |
|---|---|---|
split | A vs B comparisons | PUA式AI vs 暖心AI |
gradient | Single-topic posts | AI工具测评 |
card | Clean/minimal posts | 效率技巧分享 |
Usage
Run the generate script:
python3 scripts/generate.py \
--title "主标题文字" \
--subtitle "副标题" \
--style split \
--left-label "左侧标签" \
--right-label "右侧标签" \
--base-prompt "english prompt for AI base image" \
--output cover.jpg
Parameters
--title(required): Main title text (Chinese OK)--subtitle: Secondary text line--tagline: Bottom tagline (split style only)--style:split|gradient|card(default: gradient)--left-label/--right-label: Labels for split style--left-color/--right-color: R,G,B colors (default: red/green)--base-prompt: English prompt for Pollinations.ai base image; if omitted, uses solid color--width/--height: Dimensions (default: 1080×1440)--output: Output path (default: cover.jpg)
Examples
Split comparison cover:
python3 scripts/generate.py \
--title "同一个问题，两种AI的回答" \
--subtitle "差距有多大?" \
--tagline "一招设置反PUA人设" \
--style split \
--left-label "PUA式AI" --right-label "暖心AI" \
--base-prompt "cute flat illustration, split screen, left pink sad robot, right green happy robot, kawaii pastel" \
--output pua-vs-warm.jpg
Gradient tool review:
python3 scripts/generate.py \
--title "2026最强AI编程助手" \
--subtitle "Cursor vs Copilot vs Windsurf" \
--style gradient \
--base-prompt "futuristic code editor interface, purple blue gradient, clean minimal" \
--output coding-tools.jpg
Card style tip:
python3 scripts/generate.py \
--title "用AI写周报只需30秒" \
--subtitle "打工人效率神器" \
--style card \
--left-color "70,130,255" \
--output weekly-report.jpg
Requirements
- Python 3 with Pillow (
PIL) curlfor font download and Pollinations.ai- Internet access (first run downloads ~17MB CJK font, cached in /tmp)
Typical Workflow (for agents)
- Determine the post topic and style
- Craft an English prompt for the base image (descriptive, aesthetic keywords)
- Run generate.py with Chinese title/subtitle
- Send the resulting image to the user
